Russia is building a new spaceship they call Zeus, it's made by Roscosmos and it's a nuclear powered space tug.
It uses a regular chemical first-stage booster for going to orbit, but once in space they say it will be very fast and out run anything using chemical thrusters. Apparently Russia never stopped working on space reactors, and they do seem to be on track for meeting their timeline to get this thing operational in 2030. It's apparently meant to out-compete Spacex starship in interplanetary travel in speed and cost. It's not a direct nuclear propulsion it's a nuclear reactor powering a plasma thruster, so it's less hardcore than direct nuclear propulsion like an Orion-drive but it's also more realistic that it will actually take flight.

Does anybody know how well this will work ?

So these numbers represent the potential for starship at its peak. even in the unlikely event these numbers end up being off by a factor of 10 that would only make the sls 100x more expensive rather then 1000x more expensive. The cost savings would allow public space to focus on making and launching more nuclear ships, maybe hundreds, rather then paying out the ass just to get a couple ships to space. Spacex is going to mass produce the starship like it was an automobile, the plan is for a starship to roll off the assembly line every 72 hours. Every 72 hours a new starship capable of launching 3 times a day every day for years, thousands will be built do you not get it?

People are sleeping on this because they can't wrap their heads around the absolute scale of it, the brain simply refuses to accept it, we've been so conditioned for low expectations, happy with a couple space telescopes every few decades and maybe 2 or 3 rovers on mars, a few flybys. That's not a space age, that's a few toys and some neat pictures.

The approximate total mass to orbit, everything put into space, throughout the entire history of space travel to the present day is roughly 15 million kg. A thousand starships launching 3x a day could put that much mass into orbit in 2 months. 70 years worth of payload capacity in 2 months. 6 times the entire history of man in space every year. 60x times everything put up there so far in a decade.

There is essentially no limit, the public space program won't have to hold itself back anymore. All the space telescopes and space stations and nuclear whatevers, rovers, human colonies. Whatever the fuck we can come up with and build we can now afford to put it up there. That is a space age, and we're on the cusp on it now.

>Have you seen the cost of the sls? The latest public space heavy rocket, the costs are astronomical.
It's still private contractors that build this, so the price of this also is about subsidizing private industry.
It's not an actual example of public production because the factories that build it aren't public.

>Having nuclear balls is great but not so great when you can barely afford to put any of them into space.

It's about physics, chemical energy is not very concentrated compared to fission energy. Spacex Starship needs 9 launches to put one Starship into orbit and fully fuel it. (8 fuel launches). And with that it still can't go as far or fast as the nuclear fission powered ion-thruster in OP

>Affordable heavy lift rockets are needed, and only elons balls could provide that.

Spacex is still is de-facto subsidized by the US public. For example US Air-Force payed over 300 million to launch a spy satellite, that's approaching Space-shuttle money. That's no where near the advertised launch-cost price-tag in Spacex marketing material. Even outside of such extreme aberrations Elon Musk promised that reusable rockets would make it 10 times cheaper, but the reality is that reusable rockets economize to the tune of about 10% cheaper. That's a solid efficiency improvement considering that fundamentally it's the same technology that's been used for the last 50 years, but it's also 100 times less savings than what the Musk-fans use in their mental calculus.

It's a strange choice of words to call engineers and workers at spacex "balls"

Ok fair point about the private contractors. But if the factories were public would that actually change anything? Governments are famously bad at balancing any kind of a budget. And politics gets in the way to the point where to get approved the programs have to satisfy the demands of multiple politicians.

Spacex Starship will only need multiple launches to go beyond orbit, it can do orbit on its own. Think about it, would need to get into orbit in the first place to be refueled.
>Still can't go as far or fast as the nuclear powered thrusters
That's not the point, how are you getting those nuclear thrusters into space affordably?

The space shuttle cost $54600 per kg to orbit
The Atlas V costs $8100 per kg to orbit
Russias Angara rocket is the second cheapest option at $4000 per kg to orbit (only 2 launches to date)
The Falcon 9 is $2600 per kg to orbit
Falcon heavy is $1500 kg to orbit
https://aerospace.csis.org/data/space-launch-to-low-earth-orbit-how-much-does-it-cost/

You said Spacex is only 10% cheaper, it's more like 70% cheaper.

and the atlas v at $8000per kg is the second cheapest option available to the United States. 10% of $8000 is $800 so when people say spacex is 10x cheaper ok they're wrong, it's only 5x cheaper. But when they say 10x cheaper they're talking about a hypothetical fully reusable falcon 9, a project that was set aside to focus on the much more promising Starship.

>>11076
Of course that $20 per kg is the potential of the Starship program at its hypothetical peak with economy of scale and mass production. It won't cost $20 per kg on the first launch. And even if those estimates are off by a factor of 10 (unlikely) that's still $200 per kg ie 40 times cheaper then Atlas V rather then the projected 400 times cheaper, either way if Starship works, whatever it ends up costing per kg, it's going to be massively MASSIVELY more affordable then anything else.

People like to shit on Spacex because they saw some bullshit ragetubers lying on youtube for clicks and it satisfied them for some reason.

There's a new Jabber/XMPP server in town, running on Prosody (https://prosody.im).

prolesphere.one | d7dchu2gnb4xce7y7vwmulonr4k2wh2dmobqyitwwjeiojfotrvw37yd.onion

Registrations are open, and so is room creation. The MUC (Multi-User Chat) server is at hive.prolesphere.one

The server supports OMEMO and OTR encryption. Expect some growing pains in the early stages, there might be kinks to iron out so server may restart spontaneously. You can report any problems here in the thread or by messaging me at [email protected] (not an email).

You can find a list of XMPP clients here: https://xmpp.org/software/clients/

I use Gajim on desktop and Conversations (available from F-Droid) on mobile.

I was using riseup.net as a VPN, but, now cloudflair (The upstream provider for the site) is blocking it. Furthermore, it's come to my attention that riseup boofed their canary after the FBI requested server logs. They are glowin the darks, for real, and confirmed.
What VPN would you suggest anon? What VPN, if any, do you use. I was thinking of routing all my traffic over tor, but, currently the site still blocks tor traffic.

Help me out guys, I feel naked, thanks.

Use LUKS to set up your disk drive, then install AlienBOB's "Slackware Live" edition. Switch your repo to "-current" if it's not and grab sbopkg to simplify package installation. You're going to want dwm for your window manager.

also, the answer is lots of stores have them, like walmart, and places online ofc like the websites of carries and service resellers u can probably order active sims to be shipped
